Networking ( IP Address)

 

• 
  

Points to be Remember:-
 MAC address contain 48 bits (6 byte)

 By default IP address is IPV4

 IPV4 contain  32 bits (4 byte)

 IPV6 contain 128 bits (16 byte)

 One byte = 8bits

 By default IP address represent in Dotted Decimal Notation

 In IPV6 IP address represent in Dotted Hexadecimal Notation

 
IP Address has been classified into five classes:-
1.   Class A
2.   Class B
3.   Class C
4.   Class D
5.   Class E

IP address: - Network ID + Host ID

Class A:- 

As we know that ip address has been created and represent with the help of network id and host id. Network Id has been represent with 1 and host id has been represent with 0

In class A there are one network id and 3 host id

N Denote for Network id and H denote for host id

It will represent like:-

Class A :- 1.0.0.0 – 126.0.0.0( N. H.H.H)

Class A range lies  1.0.0.0    ---- 126.0.0.0

Class A is also called large network

In class A 10.0.0.0 this series is known as Private Class

Class B :-128.1.0.0    ---- 191.255.0.0(N.N.H.H)

                  
Class B range lies  128.1.0.0    ---- 191.255.0.0

In class B 172.16.0.0  to 172.31.255.255 this series is known as Private Class

 
Class C :-192.1.1.0    ---- 223.255.255.0 ( N. N.N.H)
                       

Class C range lies  192.1.1.0    ---- 223.255.255.0

Class C is also called small  network

In class C 192.168.0.0  to 192.168.255.255 this series is known as Private Class

 
 
Class D :-
                       
Class D range lies  224.1.1.1    ---- 239.255.255.255

Class D is used for Multitasking
 
Class E :-
                       
Class E range lies  240.1.1.1    ---- 255.255.255.255

Class E is used for Scientist Purpose

Points to be Remember:-

 127.0.0.1 is known as loopback ip address

We cannot extend the IP address more than 255

 Header Size of IPV4 is 12

 Length of IPV4 is 20

 The Header size of IPV6 is 8

 Length is Ipv6 is 40

 IPV4 is used for both multicast and Broadcast

 IPV6 is does not use for broadcast but it uses different types of multicast.

 Class A Support 16 million hosts on each of 127 networks

 Class B Support 65,000 hosts on each of 16,000 networks

 Class C Support 254 hosts on each of 2 million networks

 Class D reserved for multicast groups.

 Class E reserved for future use, or research and development purpose
